Summary: | This
paper presents one of the aspects of a wide range of challenges related to
space exploration. The main factor making it possible for humans to engage in
space exploration is the provision of a basic element of existence, which is
stable quality food. The starting point for the conducted research was the
assumption that surface phenomena, involving water and determining food
stability, can occur with different intensities under extra-terrestrial
conditions. The results of this study describe the effect of the 10 mT static
magnetic field on the process of water vapor particle adsorption and desorption
on the surface of organic samples. The research material included powders with
hygroscopic properties: gelatin (protein) and starch (carbohydrates). The
research included a comparison of the direction, dynamics, and range of water
vapor sorption in control conditions in a homogenous, static magnetic field.
The research involved the use of desiccators with aqueous saturated solutions
of NaOH and NaCl, and a static magnetic field generator. The obtained results
indicate that magnetic field has an effect on the course of sorption on organic
samples, and it can determine food stability during storage. The results of
this work also indicate that there is the potential for reducing the costs of
food preservation by drying it in the presence of a magnetic field; the study
introduces innovative solutions in the construction of cereal silos, which is part
of the concept of sustainable development. |
